This is probably the best place to start:

The following is a basic example using ASP.MVC for displaying a number of Hotels on a Google Map.

以下是使用ASP.MVC在Google Map上显示多个酒店的基本示例。

The domain object is Hotel:

域名对象是酒店:

public class Hotel
{
    public string Name { get; set; }
    public double Longitude { get; set; }
    public double Latitude { get; set; } 
}

You will need a repository to get some hotel objects. Use this in the Home controller in a method called HotelsForMap():

您将需要一个存储库来获取一些酒店对象。在Home控制器中使用名为HotelsForMap()的方法:

public ActionResult HotelsForMap()
{
    var hotels= new HotelRepository().GetHotels();
    return Json(hotels);
}

Create a partial view for the google map. Lets call it GoogleMap. It will need to contain:

为Google地图创建部分视图。让我们称之为GoogleMap。它需要包含:

Reference to the google map api

参考谷歌地图api

<script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=ABQIAAAAzr2EBOXUKnm_jVnk0OJI7xSosDVG8KKPE1-m51RBrvYughuyMxQ-i1QfUnH94QxWIa6N4U6MouMmBA" type="text/javascript"></script>

jQuery to get Hotel objects from JSON call above

jQuery从上面的JSON调用获取Hotel对象

$(document).ready(function(){ if (GBrowserIsCompatible()) { $.getJSON("/Home/HotelsForMap", initialize); } });

$(document).ready(function(){if(GBrowserIsCompatible()){$ .getJSON(“/ Home / HotelsForMap”,initialize);}});

jQuery to initialise map

jQuery初始化地图

function initialize(mapData) {

function initialize(mapData){

var map = new GMap2(document.getElementById("map_canvas"));
map.addControl(new google.maps.SmallMapControl());
map.addControl(new google.maps.MapTypeControl());

var zoom = mapData.Zoom;
map.setCenter(new GLatLng(mapData[0].Latitude, mapData[0].Longitude), 8);

$.each(mapData, function(i, Hotel) {
    setupLocationMarker(map, Hotel);
});

}

jQuery to set markers for hotels on the map

jQuery在地图上为酒店设置标记

function setupLocationMarker(map, Hotel) { var latlng = new GLatLng(Hotel.Latitude, Hotel.Longitude); var marker = new GMarker(latlng); map.addOverlay(marker); }

function setupLocationMarker(地图,酒店){var latlng = new GLatLng(Hotel.Latitude,Hotel.Longitude); var marker = new GMarker(latlng); map.addOverlay(标记); }

Finally, you will need a view that contains the partial view above. The view will need to have a div with an id of map_canvas as that is what is referenced in the initialize function above. The view should contain the following:

最后,您需要一个包含上面部分视图的视图。视图需要有一个id为map_canvas的div,因为它是上面初始化函数中引用的。该视图应包含以下内容:

<h2>Hotels</h2>
<br />
<div id="map_canvas" style="width: 500; height: 500px">
     <% Html.RenderPartial("GoogleMap"); %>
</div>

Hopefully you can use some of this, even if you are not familiar with ASP.MVC.

希望您可以使用其中一些,即使您不熟悉ASP.MVC。

It dynamically adds google map markers to a jSon file using google geocoder

它使用谷歌地理编码器动态地将谷歌地图标记添加到jSon文件
